Bacteria have to adapt constantly to survive to environmental changes. Depending on nutrient availability, the gram-positive model bacterium, Bacillus subtilis, developed an arsenal of physiological strategies such as adjusting its doubling time and its size to cope with a less favorable environment. When nutrients are lacking, B. subtilis is able to incorporate exogenous DNA or to differentiate ... in a metabolically dormant and environmentally resistant spore to wait for better conditions. In the lab, we are studying how B. subtilis adapts to these environmental signals.Lire plus Lire moins
